A heavy hydrocarbon composition with utility as a heavy hydrocarbon base stock comprising at least 95 wt.% paraffin molecules, of which at least 90 wt.% are isoparaffin, containing hydrocarbon molecules having consecutive numbers of carbon atoms, is a liquid at 100 ~C, at which temperature its kinematic viscosity, as measured by ASTM D-445, is above 8 cSt, has an initial boiling point of least 850 ~F (454 ~C) and an end boiling point of at least 1000 ~F (538 ~C), wherein the branching index (BI), as measured by the percentage of methyl hydrogens, and the branching proximity (CH2>4), as measured by the percentage of recurring methylene carbons which are four or more carbon atoms removed from an end group or branch, of said isoparaffinic hydrocarbon molecules, are such that: (a) BI-0.5(CH2>4)<15; and (b) BI + 0.85(CH2>4)<45; as measured over the heavy hydrocarbon composition as a whole.
L'invention concerne un composition d'hydrocarbures lourds utilisée comme huile de base pour lubrifiants lourds, comprenant au moins 95 % en poids de molécules de paraffine, dont au moins 90 % en poids sont des molécules d'hydrocarbures isoparaffiniques, présentant des nombres d'atomes de carbone consécutifs. Ladite composition est liquide à 100 ·C, température à laquelle sa viscosité cinématique, mesurée selon ASTM D-445, est supérieure à 8 cSt. Ladite composition présente un point initial d'ébullition d'au moins 850 ·F (454 ·C) et un point final d'ébullition d'au moins 1000 ·F (538 ·C). L'indice de ramification (BI), mesuré au moyen du pourcentage de méthylhydrogènes, et la proximité de ramifications (CH¿2?>4) desdites molécules d'hydrocarbures isoparaffiniques, mesurée au moyen du pourcentage de carbones de méthylène récurrents qui constituent au moins quatre atomes de carbone retirés d'une ramification ou d'un groupe terminal, sont tels que: (a) BI-0,5(CH¿2?>4)<15; et (b) BI + 0,85(CH¿2?>4)<45; mesuré par rapport à la totalité de la composition d'hydrocarbures lourds.
